NASA: Global Warming Is Now Changing How Earth Wobbles (go.com)
An anonymous reader writes: A new study from NASA finds global warming is shifting the way the Earth wobbles on its polar axis. Melting ice sheets are changing the distribution of weight on Earth, which has caused both the North Pole and the wobble, called polar motion, to change course. Since 1899, scientists and navigators have been accurately measuring the true pole and polar motion and for almost the entire 20th century they migrated a bit toward Canada. That migration has changed with this century -- now they're moving toward England, said study lead author Surendra Adhikari at NASA's Jet Propulsion Lab. "The recent shift from the 20th-century direction is very dramatic," Adhikari said. NASA scientist and the study's co-author Eirk Ivins said, Greenland has lost on average more than 600 trillion pounds of ice a year since 2003 and that affects the way the Earth wobbles in a manner similar to a figure skater lifting one leg while spinning.
And by "endorse", I assume you mean, "doing everything they can to kill renewable energy".

Plus, both of the leading GOP candidates for president, Donald Trump and Ted Cruz, are climate deniers.

You are welcome on my lawn.
Sea ice has expanded around Antarctica (although not so much in 2015) but sea ice has no effect on gravity because it displaces an equal amount of water to its weight. And despite a recent paper about expanding ice on the East Antarctic ice sheet the GRACE satellites show that the ice sheet overall is losing mass.
Sure, just as soon as we use a "market-based approach" to fossil fuels, instead of providing taxpayer subsidies that dwarf those for renewables.
